~Particles have “Morphology”~

When you hear “particles,” there are various morphologies.

Morphology refers to size, shape, and physical properties (transmittance and appearance), and it is analyzed through image analysis technology as“Image Analysis Based Particle Size Distribution Method (Image Imaging Method)“.

Particle image analysis is a method also described in ISO13322-1 and 2, and it is also known as Particle Image Analysis.

For example, even when indicating size, it changes significantly depending on which direction is used as the indicator.

Figure 1 below is an example of this, and the expression of directional properties also changes with the morphology of the particle.

Even when simply stating “morphology,” there are various aspects.

For example…

Figure 2

Figure 3

The particles in Figures 2 and 3 have the same “size (CE Diameter),”

but they differ when viewed by “circularity (HS Circularity).”

This means that even with the same size, the shapes can differ.

Actually, this implies something very important.

The differences in particle shape and the impact on physical properties are very important.
